I can't get the emulator to work on this computer. It already has one (had two, but I removed the other one) floppy drive. I'd like the emulator to work as drive A only (not sure I can connect two drives via one cable to the NMS825X?, but if I can, maybe later as both A+B; but for the time being I'd like to leave one real drive in place).
AFAIK the internal floppy connectors on NMS825X/80 should be standard PC type, except that you have a connector for both drives, i.e. you can't connect two drives to the same cable as on PC (at least this is the default setup); but I'm not sure. And, also disk A/B is selected by jumpers on the drives (not by twisting / choosing the connector before / after the twisted part, as on PC). You could put a PC floppy drive in, with minor modifications only (having to do with the fact that PC drives do not have any jumpers...), I think.
Has anyone set up the emulator on this computer? How did you set the Jumpers on the HxC emulator? What kind of cable did you use?
Here's what I have done / tried so far:
- I have but the .CFG file to the SD card along with a bunch of disk images converted to .HFE. I copied the files from Linux command promt to the SD card - I have no Windows (except at the walls, hehe) here so I'm not comfortable with the manager software.
- I tried with two different cables (the one that came with the MSX, non-twisted, and a PC type, with only one connector, and part of the cable twisted - i.e. "A-drive only" type cable).
- I tried all even slightly sensible seeming jumper setting on the HxF I could come up with.
- Couldn't find the NMS825X floppy connector pinouts anywhere, so can't be sure how I should set the IDx jumpers....
*Tried without the B-drive installed. Couldn't get anything to work this way
In short, here are my results: I either get the drive to work in "tandem" with the B drive, i.e. the MSX can only try to read B-drive (when trying to read A-drive, I get "Drive not ready", when reading drive B, of coure I just get an I/O error. I could boot a MSXDOS1 image, but no other images (the MSX jsut boots to BASIC and couldn't even do a file listing). From the DOS prompt, I could list the disks contents, but if I change the disk image, I will only get "Drive not ready" errors, even if I change back to the DOS disk image I just booted from! Couldn't boot any other images.
Any tips, what to try next?
